Exhibit 99.1 PRESS RELEASE, DATED AUGUST 9, 2017, OF ENERSYS REGARDING FINANCIAL

RESULTS FOR THE FIRST QUARTER FISCAL 2018

EnerSys Reports First Quarter Fiscal 2018 Results 

Reading, PA, USA, August 9, 2017 – EnerSys (NYSE: ENS) the global leader in stored energy solutions for industrial applications, announced today results for its first quarter of fiscal 2018, which ended on July 2, 2017.

Net earnings attributable to EnerSys stockholders (“Net earnings”) for the first quarter of fiscal 2018 were $48.2 million, or $1.09 per diluted share, including an unfavorable highlighted net of tax impact of $1.2 million or $0.03 per share from cash charges from highlighted items described in further detail in the tables shown below, reconciling non-GAAP adjusted financial measures to reported amounts.

Net earnings for the first quarter of fiscal 2017 were $44.6 million, or $1.02 per diluted share, which included an unfavorable highlighted net of tax impact of $5.5 million or $0.12 per share from cash and non-cash charges and credits from highlighted items.

Excluding these highlighted items, adjusted Net earnings per diluted share for the first quarter of fiscal 2018, on a non-GAAP basis were $1.12, which met the guidance of $1.10 to $1.14 per diluted share given by the Company on May 30, 2017. These earnings compare to the prior year first quarter adjusted Net earnings of $1.14 per diluted share. Please refer to the section included herein under the heading “Reconciliation of Non-GAAP Financial Measures” for a discussion of the Company’s use of non-GAAP adjusted financial information which include tables reconciling GAAP and non-GAAP adjusted financial measures for the quarters ended July 2, 2017 and July 3, 2016.

Net sales for the first quarter of fiscal 2018 were $622.6 million, an increase of 4% from the prior year first quarter net sales of $600.6 million and a 1% sequential quarterly decrease from the fourth quarter of fiscal 2017 net sales of $626.8 million. The increase in the current quarter compared to the prior year quarter was the result of a 4% increase in pricing and a 1% increase in organic volume, partially offset by a 1% decrease due to foreign currency translation impact. The 1% sequential quarterly decrease was largely due to a 6% decrease in organic volume, partially offset by a 3% increase in pricing and a 2% increase due to foreign currency translation impact.

The Company’s operating results for its business segments for the first quarters of fiscal 2018 and 2017 are as follows:

EMEA - Europe, Middle East and Africa

“We are progressing well with our new EnerSys Operating System (EOS) and product roadmap setting the groundwork for future benefits,” stated David M. Shaffer, President and Chief Executive Officer of EnerSys. “Also, commodity price recovery in our second quarter should be approximately 85% which is an improvement from our first quarter price recovery of 70%. In our second quarter, the planned increases in operating expenses including Lean, Digital Core, and product roadmap spending will outpace the anticipated savings from the new initiatives presented at our Investor Day. The team remains excited and committed about the medium and long term return on all of these investments. Our second quarter guidance for non-GAAP adjusted net earnings per diluted share is between $1.03 and $1.07, which excludes an expected charge of $0.04 from our ongoing restructuring programs, ERP system implementation and acquisition expenses.”

Reconciliation of Non-GAAP Financial Measures

This press release contains financial information determined by methods other than in accordance with U.S. Generally Accepted Accounting Principles, ("GAAP"). EnerSys' management uses the non-GAAP measure “adjusted Net Earnings” in their analysis of the Company's performance. This measure, as used by EnerSys in past quarters and years, adjusts Net Earnings determined in accordance with GAAP to reflect changes in financial results associated with the Company's restructuring initiatives and other highlighted charges and income items. Management believes the presentation of this financial measure reflecting these non-GAAP adjustments provides important supplemental information in evaluating the operating results of the Company as distinct from results that include items that are not indicative of ongoing operating results; in particular, those charges that the Company incurs as a result of restructuring activities, impairment of goodwill and indefinite-lived intangibles and other assets and those charges and credits that are not directly related to operating unit performance, such as fees and expenses related to acquisition activities, stock-based compensation of senior executives, significant legal proceedings, ERP system implementation and tax valuation allowance changes. Because these charges are not incurred as a result of ongoing operations, or are incurred as a result of a potential or previous acquisition, they are not as helpful a measure of the performance of our underlying business, particularly in light of their unpredictable nature and are difficult to forecast.

Income tax effects of non-GAAP adjustments are calculated using the applicable statutory tax rate for the jurisdictions in which the charges (benefits) are incurred, while taking into consideration any valuation allowances. For those items which are non-taxable, the tax expense (benefit) is calculated at 0%.

This non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for Net Earnings determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of the Company's results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies. Management believes that this non-GAAP supplemental information will be helpful in understanding the Company's ongoing operating results. This supplemental presentation should not be construed as an inference that the Company's future results will be unaffected by similar adjustments to Net Earnings determined in accordance with GAAP .

Included below is a reconciliation of non-GAAP adjusted financial measures to reported amounts. Non-GAAP adjusted Net Earnings are calculated excluding restructuring and other highlighted charges and credits. The following tables provide additional information regarding certain non-GAAP measures:

The following table provides the regional allocation of the non-GAAP adjustments shown in the reconciliation above:
